Troj/Small-DP is a Trojan downloader for the Windows platform.

When run the Trojan attempts to download files from the Internet to the files C:\t.exe, C:\n.exe or C:\m.exe and run them.

The Trojan also tries to create the following registry entries so as to run itself on computer startup:

HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce
Local runole service
%SYSTEM%\srvc32.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
Local runole service
%SYSTEM%\srvc32.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Local runole service
%SYSTEM%\srvc32.exe

In order to stealth itself, the Trojan also attempts to inject itself into the Windows Explorer process.
